Blackra1n is a great jailbreak tool for iPhone 2G, 3G or 3GS running OS 3.1.2. It’s simple and quick. But it does come with some bugs. After jailbreak your iPhone using blackra1n, you may encounter one of the below issues:

  • Fail to launch YouTube
  • GPS doesn’t work if you’re using iPhone 3G/3GS
  • WiFi is not working
I guess GeoHot, the developer of blackra1n, will fix these bugs in the next version update. However, at the mean time, you can follow these workarounds to fix the issues. Perhaps it may help you for this moment.

How To Fix WiFi Issue

To fix the WiFi issue after blackra1n issue, you can simply reset the network settings. Go to “Settings” -> “General” -> “Reset” and select “Reset Network Settings”. Tap on the “Reset Network Settings” button again to confirm. After resetting, the WiFi issue should be fixed.

How To Fix YouTube and GPS Issues

It’s very interesting the PushFix patch, which is originally designed for fixing push notification, can be used to fix the YouTube and GPS issues. After patching with PushFix, your iPhone should be able to use YouTube and GPS.
